A new campaign backed by former President Barack Obama is alleging "gerrymandering has been in America's DNA for some time now." Gerrymandering is the partisan mapping of voting disctricts so that they favor a political party.

An ad by the "All on the Line" group calls for states to allow fair voting rights by preventing "voter suppression." Obama-appointed Attorney General Eric Holder appears in the ad, stating, among other things, that "in 2011, when Republicans drew the lines for the next 10 years was the worst example of gerrymandering in many years..."

“With fair maps and a more just electoral system, we can have leaders who are more likely to tackle the important issues facing our country and be more responsive to the needs and desires of the people they were elected to represent”, Holder stated.

"For too long, gerrymandering has contributed to stalled progress and warped our representative government. Redistricting begins next year—let’s all do our part to protect and restore our democracy," tweeted Obama.

Those opposing the group claim Obama and Holder are making the accusations to allow them to gerrymander in favor of the Democrat party.
